Is there a difference between a 5.4 lightning block and just a stock 5.4 block?

 

none

 

Same block,same heads,same rods.50%- 50% chance on the same crank.
The L has forged pistons.

Thanks guys, also are these heads fixable?

 

Yes- But I would definitely do some price checking as it may be more cost efficient to purchase a set a new assembled heads versus saving those- but it all depends on the machine shop and their cost which is "very regionalized"

 

well i can pick those heads up for about $300 and they're stage II lightning heads and i know a new pair is about 1600 so i was seeing how that compare in pricing

 

no to machine that damage out would change the CR ratio on that cylinder. make for balancing nightmare. also looks like the valve is bent and i bet theres a damaged valve seat
